SUPlPORT FOR CEMENTITIOUS BLATERIAL.

Application filed. August 5, 1314.

To all whomit may concern.

Be it known that l, l lnxns'r Frisco, a. citizen of the United States, and a resident of the city of New York, borough of Manhattan, county and State of New York, have invented a new and improved Support for (.ementitious Material. of which the following is a full. clear, and exact description.

My invention relates to means adapted to form supports for cemcntitious material partitions while the same are in process of setting.

My invention relates more particularly to vertical supports which will carry the plastic mass and which will permit the same to plumb under the action of gravity.

My invention further relates to vertical supports for cementitious material which will contract under the action of the luv n idity present in the plastic mass when the same is applied to the support.

The object of my invention is to provide a simple. inexpensive, and flexible support which is adapted to be embodied in the body of the structure and form carrier therefor until the plastic material sets.

\Vith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate correspondin" parts in all the views. and Figure l is a flee elevation of a vertical support for cementitious material embodying my invention; F ig. 2 is an enlarged fragmentary view thereof; Fig. 3 is a vertical, enlarged section on line 3-3, Fig. 1; Fig. 4 is an enlarged section of the fibrous material used for the supportpFig. 5 is a modified structure of the support; and Fig. 6 is a further modification thereoi.

Referring to the drawings, 5 represents the cross section of a building which is to be provided with a partition; 6 are the anchoring means secured to the top, sides and bottom of the Wall where the partition is to be formed; and 7 shows a door jamb which is to; be incorporated in the partition. The support or carrier 8 is formed of fibrous netting sections 9 suspended from the top anchors by suitable means, as shown in Fig. 1, by a twine 1O engaging alternately the anchoring means and the upper edge ofthe Specification of Letters Patent.

netting. It is evident that the support, if desired. can be made of a single section in place of a number of sections. The adjacent edges of the netting sections are also united by twine 11, or any other suitable means. The support 8 hanging from the upper anchor G is then made taut by a twine 1? drawing the side edgesof the support against the sides of the wall by the engagement with theanchors provided therein. The bottom edge of the support is also drawn toward the bottom anchors by means of a twine 13 made to engage the support and the anchors. It is understood that any other suitable means may be used for making the support taut between the walls where the partition is to be. formed, and similar means may be used to draw the edges of the support 8 to the door iamb, The support can then be covered with -a,plastic ceinentitious material from both sides so that the support 8 is incorporated within the body of the partition to be formed. The support is in its nature flexible and the plastic material carried thereby will move it to the vertical position under the action of gravity if the said support was not originally in a vertical position.

in general the vertical supports for cementitious materials must he very taut; and a great. deal of time and care is expended to make such support as taut as possible. In my structure there is no necessity for making the support very taut. as being of a fibrous nature it contracts under the action of humidity present in the plastic material when the same is applied to the support, thus increasing greatly the tantnessof the support between the walls and eliminating thereby the tedious work and necessary care to be exercised to make the support taut. It further eliminates the great care necessary for placing the support for the plastic material. exactly vertical, for the reasons above stated.

In Fig. 5 a modified structure of the support is shown. In this modified structure the support 8' is formed of a series of longitudinal. flexible. fibrous members 15 loosely suspended between the upper and lower anchor 6'. each of the members 15 being double. The facing portions of said longitudinal members 15 on the adjacent anchoring means are united to each other by suitable clamping members 16, thereby forming a netting, the members of which are ren:

dared taut hi the clamping means 16. The tautncss of these members will further increase when .the plastic material is applied thereto under the action of the moisture present in the plastic material.

When the nettin formed b the members 15 is coarse, the same is preferably covered with fine fibrous netting sections 17, which sections can be secured thereto in any suitable way. (See Fig. 6). Preterably the consecutive netting sections are secured to the opposite sides of the fibrous members 15; that is to say, the consecutive sections of the fibrous netting alternate on the sides of the coarse netting formed by the fibrous members 151'. At all events, the support for the cementitious material is a fibrous netting,so that the tautness of the. support increases as the plastic material is applied thereto.

Having thus described my invention, I

claim as new and desire to secure by Letters fibrous elements adapted to contract under the action of the humidity present in the plastic mass while the same is setting.

A flexible vertical support for unset cemcntitious'material structures which is adapted to contract while the plastic mass is, setting thereon.

5. A vertical support for unset cementitious material structures which comprises a plurality of anchoring means and flexible members secured-to said anchoring means and made taut there-between, said flexible members bein adapted to contract under he action of he moisture present in the lastic mass when the same is applied to the support. i

6. 'A vertical -support for 'unset cementitious material. structures which comprises anchoring means, fibrous netting, and means connecting the fibrous netting to the anchoring members.

-8. A'vertical support for unset cementitious material structures which comprises anchoring means, fibrous members connecting said anchoring means, means for making said members taut on said anchoring means, and a fibrous netting secured to said fibrous members.

9. A vertical support for unset cementit-ious material structures which comprises anchoring means, fibrous members engaging said anchoring means, means for rendering said members taut between said anchoring means, and fibrous netting sections securedto said fibrous members, the consecutive fibrous sections being adapted to be on the opposite side of said fibrous members.

10. A shrinkable support for cementitious material structures, including anchoring means for said support, said support being susceptible to the moisture in the plastic mass of the cementitious material when it is setting thereupon.

I 11. A support for cementitious material structures, which comprises anchoring means, shrinkable, flexible members secured to said anchoring means, said flexible members becoming taut on the anchoring means under the influence of the moisture present in the plastic mass of the cementitious ma- 1 terial. when the same is u )lied to the su ennnsr FLAGG.
